METHOD OF CAPPING BOTTLES.

No Drawing.

To all whom it may concern:

Be it known that. I, JOHN WYSOCKI, a citizen of the United States, aresident of Brooklyn, in the county of Anne Arundel and State ofMaryland, have invented a certain new and useful Method of CappingBottles, of which the following is a specification.

This invention relates to a capping a bottle.

An object of the invention is the provision of a suitable method forforming a cap over the cork and neck of a bottle to rovide an air-tightclosure of the same which may be readily removed when the contents ofthe bottle are to be used.

The invention may assume various'specific forms, and the followingdescription constitutes merely a preferred embodiment of the invention.This composition in one of its preferred forms consists of 100 gramsnitrocellulose such as pyroxylin, 500 c. c. ether, 500 c. c. absolutealcohol, 50 c. c. castor oil, 30 grams aluminum powder,

and a suitable quantity of a yellow aniline dye. This composition hasbeen designed to provide a suitable viscosity so that the compositionwill spread uniformly over the surface of the bottle and dry to producea very neat and glossy appearance. It will be understood that theproportions may be varied somewhat while retaining the desired viscosityand that equivalents may be substituted.

l The bottle to be coated with a cap is filled with the liquid intendedto be marketed. the cork is properly inserted. and the neck of thebottle is then provided with a thin coat ing of vaseline, after which itis dipped into the above coating composition while the composition isbeing agitated by any suitable means in order to insure homogeneity.After each dipping-the coating formed on the neck of the bottle and overthe cork is method of allowed "to dry before dipping for the nextcoating, and these dippings are then continued until acap of the desiredthickness is obtained. In order to quickly dry the successive coatings.a gentle air blast having :1 temperature of 25 to C, is employed. Thecoating may be made very smooth and neat in appearance by dipping theneckof the bottle with the coating thereon into cool Application filedDecember 29, 1921. Serial No. 525,809.

- water for one or two seconds after each coating.

.Before applying the coatings as above described, there may be applied asub-coating formed of a composition comprising the followingconstituents: grams nitrocellulose such as pyroxylin. 500 c. c. ether,500 c. c. absolute alcohol, 25 c. c. castor oil, grams aluminum powder,and a suitable quantity of a yellow aniline dye. This coating provides adull non-transparent basic layer containing a higher ratio of metallicconstituent. The constituents of these coatings may be varied bysubstituting various cellulose esters or other preferably transparent ortranslucent coating material for the nitrocellulose, various solventsfor the ether and alcohol, suitable softeners in place of cast-or oil,and other metallic powders and non-corrosive or tarnishing substances inplace of the aluminum powder. Other suitable greases or oils may ofcourse be substituted for the Vaseline as long as they will have theproperty of preventing too close an adhesion between the composition.and the glass.

While the bottles arebeing dipped. it is advisable to rotate them eitherby hand or by machinery so that the coating will be uniform inthickness. and this rotation may be continued after the bottle has leftthe coating liquid so that the latter will spread uniformly whiledrying.

As a result of the above described method of procedure. a bottle cap isformed over the cork and on the end of the neck of the bottle, which isair-tight. and not affected by atmospheric influences. that is. it willnot tarnish or corrode. It may easily be stripped off because of theunderlying film of Vaseline or' other greasy material, and it willresemble a metallic cap in many respects. The dye employed will colorthe entire composition so that the metallic particles will appear to beone continuous sheet of metal as the metallic'particles will reflect thecolor of the dye without being themselves colored. This will produce auniform color without employing a colored metal or alloy of adestructible or nonpermanent nature.

As many apparently widely different embodiments of this invention may bemade 2. The method of capping a bottle com- 15 prising applying theretoa solution having a viscosity enabling it to spread uniformly over thesurface, this solution containing the following ingredients in thefollowing approximate relative proportions: Ether, 500 c. 0.; alcohol,500 c. c.; castor oil, 50 c. c.; aluminum powder, 30 grams;nitrocellulose, 100 grams.

In testimony that I claim the foregoing, I have hereunto set my handthis 5th day of 25 December, 1921.
